Removed some methods that are unused from af-events.cpp

[andy31415]

Problem

Unused code. Af-events usage is unclear since af-gen-events.h currently is not generated yet it seems a required include sometimes generated as empty by our build infra.

Change overview

Remove some unused code in the repo, trying to simplify the amount of code we have to review and maintain.

Testing

Grepping said that this code is unused. CI will validate that things still build.

fast track because this is pure unused code deletion (and I see no plans to actually use this code in the future ... we should migrate away from using events from timers and only use system timers for consistency and simplicity - less generated code)
